It's an expression, that's how it's "build"- out of something, not out from something.
For example: I'm out of my mind/ out of my way / out of my heart / out of reach / out of control / out of the blue (de repente).
"out" requests "of" after. Saying 'out of' is commonly used when you have used up all of something (i.e. there isn't any left).
